Q = 7m + 3n
R = 11 - 2m
S = n + 5
T = -m - 3n + 8
simplify Q + S - T
7m + 3n + n + 5 - (-m - 3n + 8) =
7m + 4n + 5 + m + 3n - 8
8m + 7n - 3 <====
Answer:The radius of Betelgeuse is about 5 × 1011 meters, and the radius of Venus is about 6 × 106 meters.
Step-by-step explanation:
because the 500 billion Has 11 0s so it will be 5 x 10^11
